Hb AS — Sickle cell trait
Hb AA — Normal adult haemoglobin
Hb AS — Sickle cell trait
Hb SS — Sickle cell disease
Hb SS — Sickle cell disease
Important: On cellulose acetate electrophoresis at alkaline pH, Hb A migrates farther towards the anode than Hb S, while Hb F remains closer to the cathode/origin. The bands in lanes 1–5 appear to show different combinations of these haemoglobins, but the exact genotypes cannot be confirmed confidently from this photograph alone without reference controls or the answer options.
